Abstract
The invention relates to a filtering device for filtering fibrous material from water flowing through a channel, the device comprising a sieve, the sieve being arranged at an angle with respect a flow direction defined by the channel. According to the invention, said angle is smaller than 25°. The invention also relates to a method of installing such a filtering device, a system comprising such a filtering device, and the use of such a device.
Claims20
A method of installing a filtering device for filtering cellulosic fibers from water flowing through a channel, the method comprising:
- installing a sieve in the channel at an angle with respect to a flow direction defined by the channel, the sieve having an aperture size of from 0.8 mm to 10 mm, and
- wherein said angle is smaller than 25°, the method comprising allowing a buildup of filter cake on an inlet side of the sieve.
A method for removing cellulosic fibers from water, the method comprising:
- using a filtering device for removing the fibers from the water, the filtering device being for filtering fibers from water flowing through a channel, the device comprising:
- a sieve, the sieve arranged at an angle with respect a flow direction defined by the channel, the sieve having an aperture size of from 0.8 mm to 10 mm,
- wherein said angle is smaller than 25°, the method comprising allowing a buildup of filter cake on an inlet side said of the sieve.
A method for removing cellulosic fibers from water, the method comprising:
- using a filtering device for removing the cellulosic fibers from the water, the filtering device being for filtering the cellulosic fibers from water flowing through a channel, the device comprising:
- a flat and perforated sieve, the sieve being arranged at an angle with respect a flow direction defined by the channel, the sieve having an aperture size of from 0.8 mm to 10 mm,
- wherein said angle is smaller than 25°, the method comprising allowing a buildup of filter cake on an inlet side said of the sieve,
- wherein the filtering device further comprises at least one wiper which is movable over and/or across the sieve,
- the filtering device further comprising means for preventing and/or limiting tilting of the wiper with respect to the sieve.
